Lette/rs Patent No. 83,233, dated Octoberl 20, 1868. d

IMPROVED PQST-ATJ'GER.

The Schedule referred to in these Lette To all whom it may concern:

' Be it known that I, CALVIN ADAMS, of the city of Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invented a new and improved Post- Auger, an implement forv boring or digging holes in the earth, to set posts in; and I do hereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, making partof this speciiication.

This post-auger may be ,made of cast or wroughtiron, -sheet-iron, or steel, or a combination of these materials; but I generally make them of cast-iron, and will particularly describe my method of so constructing them. The drawings show an auger made' with an opening or recess, A, in the centre, in which the wooden handle, B, is to be inserted and fixed. They may be made, however, with ironhandles constructed either as a part of or to be attached to the auger. The disk or boring-surface of the vauger I form in one or more parts, which may properly 'be called blades or arms, O, O C C, with open spaces of about an inch each between each arm, D D D D, for the earth to pass through. The arms C C are pitched forward, or set at an angle suiicient to takenp the earth as it is loosened in turning the auger. p On the face or front edge, c c c a, bf these arms, vI'formone or-more V-shaped plows, E E

`E E, for the purpose of tearing and loosening the ground moreA easily and rapidly than could be done by the plain edge of the arm, andthereby reducing the It will be seen by the drawings that I have placed one of these plows on eachof the four arms therein shown, and at dierent distances from the centre, A of the auger, so that each plow makes'its own furrow, and all the surface underneath the arms is thus loosened and taken up on' the arms at every revolution of the anger. I generally make these plows, E E E E, like the other parts of the anger, of cast-iron, and the auger thusvmade is ca'st in one entire piece, with or without a handle; but the manufacturer may, if it is preferred, make the plows of steel, and rivet or otherwise fasten them on to thewarms. 0f course, be made with less or more arms, and fewer or more plows than I have described. I make these angers about eight 'inches in diameter, and the plows a half an inch or more in depth at the edge a, sloping from thence up, so as to carry the earth easily on to thearmsGC.

Having thus described the nature and use of my invention,

That I claim as new, and desire to secure by Letters Patent, is

A post-auger, with one or more plows, constructed and arranged on the arms, and operating substantially as -and for the purpose shown and described.
